Semen attributes and their association with fertility in Beetal bucks was assessed. Three ejaculates per buck (n=14) were analyzed for sperm functional tests, malondialdehyde concentration (MDA), antioxidant enzymes. Seminal plasma was analyzed for testosterone and total proteins. A significant (p<0.05) difference in individual motility, viability, plasma membrane integrity (PMI), acrosome integrity (AI), MDA and antioxidant enzymes among the bucks was observed. There was also a significant (p<0.05) variation in total protein and testosterone levels in seminal plasma. A fertility rate of 100%, 83.3 %, 66.7 % and 50% was found in 3, 4, 5 and 2 bucks, respectively. Bucks were divided into high (G-I, 83.3-100% FR) and low (G-II, 50-66.7% FR) fertile groups. Average sperm concentration, individual motility and viability, were significantly (p<0.05) high in G-I compared to G-II. Average MDA concentration, super oxide dismutase, catalase and glutathione reductase were significantly (p<0.05) high in G-II compared to G-I. Average values of total protein and testosterone were significantly (p<0.05) higher in G-I and G-II, respectively. Study concluded that oxidative stress and testosterone level has an impact on semen quality and fertility of Beetal bucks.
